Today I logged into the new cisco program which is called Working at a small to meduim Business or ISP and starting reading at 1.1.
Here are some relevant points that I read today:
- The Internet has grown rapidly, and is now global. New technologies are continuously being developed that make the Internet easier and more attractive to use. Online applications are available to the Internet user, including email, web browsing, streaming music and video, gaming, and instant messaging.
- Electronic commerece buying or selling on the internet
- standard is a set of rules that determines how something must be done. Networking and Internet standards ensure that all devices connecting to the network use the same set of rules. Using standards, it is possible for different types of devices to send information to each other over the Internet.
-Point of Presence (POP) - A business has the option of connecting to the ISP through POP, using a variety of access technologies.
-Equipment co-location - A business may opt to have some or all internal network equipment physically located on the ISP premises.
-Dialup access
Dialup access is an inexpensive option that uses any phone line and a modem. To connect to the ISP, a user calls the ISP access phone number. Dialup is the slowest connection option, and is typically used by mobile workers and in areas where higher speed connection options are not available.
DSL
Digital subscriber line, or DSL, is more expensive than dialup, but provides a faster connection. DSL also uses telephone lines, but unlike dialup access, DSL provides a continuous connection to the Internet. This connection option uses a special high-speed modem that separates the DSL signal from the telephone signal and provides an Ethernet connection to a host computer or LAN.
-Cable modem
A cable modem is a connection option offered by cable television service providers. The Internet signal is carried on the same coaxial cable that delivers cable television to homes and businesses. A special cable modem separates the Internet signal from the other signals carried on the cable and provides an Ethernet connection to a host computer or LAN.
-Satellite
Satellite connection is an option offered by satellite service providers. The user's computer connects through Ethernet to a satellite modem that transmits radio signals to the nearest Point of Presence, or POP, within the satellite network.
-
T1 connections transmit data up to 1.544 Mbps. T1 connections are symmetrical, meaning that the upload bandwidth is the same as the download bandwidth. A medium-sized business may need only one T1 connection. E1 is a European standard that transmits data at 2.048 Mbps.
-
T3 connections transmit data up to 45 Mbps. Although considerably more expensive than a T1 connection, larger businesses may need a T3 connection to accommodate the number of employees. Large businesses with multiple locations might use a combination of T1 and T3 lines. E3 is a European standard that transmits data at 34.368 Mbps.
Metro Ethernet offers a wide range of high-bandwidth options, including Gbps links. Large companies with many branches in the same city, such as banks, use Metro Ethernet. Metro Ethernet connects the main office location and all the branches using switched technology. Metro Ethernet allows the transfer of large amounts of data faster and less expensively than other high-bandwidth connection options.

Relevant points that I read about today:
-Customer Service receives the order from the customer and ensures that the specified requirements of the customer are accurately entered into the order tracking database.
Planning and Provisioning determines whether the new customer has existing network hardware and circuits and if new circuits need to be installed.
The On-site Installation is advised of which circuits and equipment to use and then installs them at the customer site.
The Network Operations Center (NOC) monitors and tests the new connection and ensures that it is performing properly.
The Help Desk is notified by the NOC when the circuit is ready for operation and then contacts the customer to guide them through the process of setting up passwords and other necessary account information.

Today we watched videos about how to install a windows operating system but I already installed a Linux Ubuntu operating system on my laptop so I have some experience and knowledge. I have a dual-boot on my laptop, just saying. Then the rest of the we finished rebuilding our computers. I finished mine and then I gave a helping hand to others in need.

Today I logged on cisco net cad and went into my grade 12 cisco course and read the summary. Then I wrote the quiz and I knew I was ready because I knew most of the content.
Friday Sept. 16th 2011:
Today we logged on cisco and then we read a bit. Then I wrote my first cisco grade 12 test. When I was finished my test, I helped to fix Mr.brooks computer because it wasn't turning on so we decided that the power supply broke and must be replaced with the same model.
